update_kernel: be smarter

update_kernel: be smarter

Auto-detect use of verity, and if verity is not used, copy over modules and firmware.

Also, while I was at it, I added a --noreboot argument.

And also copy over vmlinux.uimg on ARM if on non-verity.

Why would you not want to reboot?

Mostly useful when testing the script, but seemed useful to add as an option
instead of patching the script every time. I can take it out if you prefer.

I guess leave it in until the script is stable. Just nice to keep options
to a minimum.
